My dad was watching a show last night called "Million Dollar Guns" on the history channel and his gun was on there. Its a Colt Pocket Model Paterson Revolver, 28 caliber. 500 were made in 1837. Its been in a bank deposit box since ~1950.
So this morning my dad asked him to find a place to 'authenticate' the gun, and to 'clean it up'. Where would I even begin, a gun-store?
